ttl

Optional time-to-live specifying how long the pool definition should be cached. The cache has two purposes:

  • To limit the number of configurations kept in memory at any one time
  • To enable data to be refreshed from external storage, such as a json data file, or a database

The default TTL is 60 seconds, but you can specify any duration using a string like "5 mins" to specify 5 minutes.
